Sunrise alarm clocks are pretty cool, but they tend to cost around $70-$200. How-To Geek points out that those specialized clocks are pretty unnecessary. A smart light bulb can do the same thing.

Most smart bulbs come with starter kits for around $25-$80 and they all have software that can mimic the effect of a sunrise alarm clock. You can then use the bulbs in your nightstand light or your overhead lights, whichever you prefer. It’s a pretty simple set up and a great use for those smart bulbs that you might already have around. Head over to How-To Geek for guides on setting up the system on a Philips Hu, Belkin WeMo, and the Wink.
